I know the fundamentals of biamping, however I cannot for the life of me find if there is a standard crossover frequency for receivers that offer a biamp feature? It doesn't mention it anywhere in my RXV667 / HTR-6063 manual... I am just wondering because I am going to build floorstanders, and it would save me time and money to know where the biamp crossover frequency is..

Receivers typically don't provide a crossover with their bi-amp feature. Bi-amping in this case means sending two full-bandwidth amp outputs to the same speaker where the are input to the speakers high-order crossovers. Doesn't really do too much IMO.

oh okay that makes sense, I was under the impression that there was a high-frequency side, and a low-frequency side. And that 1 amp would only put out the low frequencies, while the other amp would only put out the high frequencies. So in a way it would choose the crossover, without the need for a passive crossover in the speaker. But that makes sense

If you want an avr with an actual adjustable crossover for biamping there are some, like the Onkyo 818, which can be useful in a situation like you building your own speakers....

my god, there is such receiver!
the onkyo 818 indeed have such function, named digital processing crossover network.
there's no features such as changing the crossover slope, crossover type, limited to only a few point and the tweeter level only range from -6db to +6db.

not full featured as a proper dsp but it will work. thanks for bringing this up.

When AVR manufacturers talk about bi-amping, almost always they are talking about sending two full-range amplified signals (minus the LFE) to the same main speaker. This is what I thought you were originally asking about. If you're talking about separating the LFE and low-bass from the other main and surround channels to send to a subwoofer, that is called bass management. Every receiver sold today with more than 2 channels has bass management.

You know what, I just got to playing with the PEQ in my amp - HTR6063/RXV667 - and it does EACH speaker individually. I can actually modify the PEQ of the biamped section as well, which essentially I have set at 100hz cutoff, and the regular left/right are cut off at 125hz which both overlap and fill the gap. I must say this makes quite the difference in sound, much smoother!

Thanks, didn't know that! I guess that's called passive biamping?

Ok thanks. I have a feature called "extra bass" on my receiver and it sends all bass info to the main minus LFE, then the subwoofer gets the regular LFE and full bass as well. But through parametric EQ the mains can be modified.

On another note, if I set my amp to 5.1/Biamp, and select "no subwoofer", will it send the LFE to the mains? (EDIT: Yes, just searched the manual!)

Not being able to adjust slopes and the +/- 6db adjustment is not going to work for very many people using a compression driver, but I will say, it is a surprise feature.
